Cleaning equipment and vehicles for sensors

Abstract

A cleaning device and vehicle for sensors are provided that can enhance the cleaning effect of the sensor surface. [Solution] The invention comprises a valve assembly coupled to the exhaust end of at least one gas storage tank and including a plurality of valve outlets, which is controlled to open or close an airflow passage between the exhaust end and at least one of the plurality of valve outlets, and a plurality of nozzle assemblies, each having a nozzle inlet and at least one nozzle portion communicating with the nozzle inlet, wherein the nozzle inlets are coupled to corresponding valve outlets among the plurality of valve outlets, and at least one nozzle portion is positioned adjacent to a sensor, so as to inject a gas at a predetermined pressure into the sensor to clean the sensor when the corresponding airflow passage is opened.
